When collecting freshly spun artificial silk on bobbins, reels-or the like, the thread is laid spirally on the bobbin or other member on which it is collected by means of a reciprocating thread At each limit of the transverse movement of the thread guide, the direction thereof 1s reversed, and if this reve'rsal is effected more rapidly, a better building-up on the bobbin takes place, which also tends to lessen undesirable .accumulations of thread at each end of the bobbin, which are diicult to wash. However, the quick reversal of the thread guide at each end of the bobbin gives rise to irregular deformations of the thread, and, consequently, to differences in colour when dyed. These differences in colour are very troublesome both in the hosiery and weaving industry, because they occur at ,regular intervals and may, consequently, produce undesired streaks or patches of different colour in the goods at regular intervals.

It has now been found that a quick guidance of the thread during the reversal of movement at the ends of the bobbin may be allowed to take place and the harmful effects of the reciprocating movement of the thread guide on the dyeing qualities of the finished product can be avoided by superimposing an undulating movement on the periodic reciprocating movement of the thread guide. When this is done, the thread is not only wound spirally on the bobbin, -but it is wound in a wave-like form at the same time. This form of winding has the advantage that, even with a slow traversing movement of the thread guide,

a sufficiently firm coil is obtained and the washing can proceed more advantageously.

For this purpose the periodically oscillating thread traversing device is made of elastic construction at a suitable place, so that the thread guide or the mechanism which drives the thread guide, or a group of thread guides, is able to make an additional free springing movement. This additional movement is at times neutralized and at times excited afresh in an irregular manner by the pendulum stroke of the driving mechanism.- Both oscillatory movements, namely the main traversing movement and the freely vibrating movement of the thread guide together result in the thread being wound on the bobbin or the like in an irregular wave-like form.

Some constructional embodiments of apparatus in accordance' with the invention are illustrated diagrammatically by way of example in the accompanying drawing, in which Figure l shows a spooling device in which the thread carrier is swinging from one end of the spool to the other end.

Figure 2 shows a similar device in which however the thread carrier reciprocates from one end of the spool to the other end on a straight line.

Figure 3 again shows a spooling device provided with a thread carrier swinging to and fro. The

shaftmoving the thread carrier and swinging about its own axis is d ivided into two parts which are connected to each other by an elastic coupling member.

Figure 4 again sho ws a spooling device provided witha thread carrier swinging to and fro and the shaft of which swings about its axis and is rigid in itself whil'e it is elastically coupled with the driving arm.

Referring 'to Fig. 1

the 'artificial' silk bobbin l' is wound with the thread 2 which passesthrough the thread guiding eye Referring to Fig. l, on

the driving axis 4, which rotates backwards and forwards, is mounted the pendulum or swinging arm 5 which is `oi' strong and rigid construction at its upper end, whereas it tapers towards its lower end to which is attached a steel wire 6, the end of which is provided with the said thread guiding, eye 3. The driving arm 8 forms with the 5 a rigid set which movement the driving end 8a engages a pin 9 known type.

lation and the stroke of an adjustable weight In thedevice shown pendulum or swinging arm swings to and fro about the driving axes li. In order to accomplish this arm 8 with its upper forked a of the rod 9 which is continuously reciprocated by a suitable drive of any For regulating the period of oscilthe vibrating steel wire 6 1 is fitted on the wire. by Fig. 2 the arm 5 is rigidly connected to the rod i4 and is not caused to swing about a swinging axle but a horizontal direction by the saidY ciprocated in rod l5. The oscillating arm end with forks l5a which In the device shown by Fig. 3 the shaft imparts an oscillatory arm l'lisY divided into connected to each other The engagement member l0.

I4 which rod isdriven only continuously rehalves is produced by two rubber blocks I l so that the portions .ita and l 6b of the shaft are allowed to slightly displace angular-ly with respect to eachother and the eye 3 o f the thread carrier is free toV to accomplish a vibratory motion besides its regular oscillation. f

In the device show by Fig. 4 the Shaft I9 s rigid in itself and carries a pin I3 keyed to it. With the driving arm I8 pin I3 is connected elastically by a rubber sleeve I 2 extending over the ends of either arm, which also permits a vibratory motion of the thread carrier eye 3 besides the regular oscillation of the same.

In all forms of construction the maximum stroke of the thread guide may be limited by a suitable stop 20.
